NASA's Curiosity Rover Successfully Lands on Mars

The Mars Science Laboratory Rover 'Curiosity' has successfully landed on Mars after a grueling 7 minute descent involving a 'Skycrane' landing system which had never been tried before on a space mission.  Curiosity is the largest robotic rover ever to be sent on a planetary mission, and has the largest scientific payload by mass.  It sent back the first surface images (including the one shown at right) soon after touchdown.  Curiosity will spend the first few days testing systems and surveying the surrounding terrain, before commencing its journey across the surface.
